Re: Magentostatic Problem

Hi, I am not familiar with magnetostatic simulation. To rule out a postprocessing problem: Your simulation does write a file case.vtu, which ElmerPost cannot display. For ElmerPost you would have to change the output file extension to .ep in Model>Setup. But ParaView is the recommended postprocessin...

Re: Using Elmer as a library from an external software

Ok, then using Elmer instead of your custom FEM solver might be an option. You will need to prepare a mesh, build a sif file, launch the solver and import the result back into your program. How much work this will be depends on what is already implemented in your program. If you need more informatio...

Re: Elmer crash when clicking on boundaries

Hi,

do you use a nightly build or the release version?
I don't have those crashes at the moment under Windows 7 using a nightly build dated 2018-08-01.
If the crashes persist, all you can do is not to doubleclick on your mesh, export it to gmsh and examine it there as described above.

HTH,
Matthias

Re: Using Elmer as a library from an external software

I see. Note that Elmer provides mainly the FEM solver. So for preprocessing (geometry definition, meshing) and postprocessing (results analysis and display), you will need additional software or do it with your own program. There are attempts to use a FEM solver (Elmer or other) from within other so...

Re: Using Elmer as a library from an external software

What would be the advantage of using Elmer as a library?

Re: Using Elmer as a library from an external software

Hi,

ElmerSolver is (mostly?) written in FORTRAN. I think the best and simplest way to go is to let your software write a sif file and launch ElmerSolver using a system call.

HTH,

Re: Surface as a body in 3D

This must be done in Elmer. I had not remembered quite correctly, it is currently possible only in the Heat solver, see http://www.elmerfem.org/forum/viewtopic.php?f=11&t=4210#p14890 . I am not sure if it can be done within the GUI. Anyway, AFAIK it is currently not possible for the Static Current S...

Re: Surface as a body in 3D

N.B. It would be practical to be able to use a surface as a body giving it a thickness in the Elmer settings, so that thin layers can be simulated without too much challenge in meshing. AFAIK this is currently only possible in mechanics, not in electric simulations.

Re: Surface as a body in 3D

Hi,

I am not sure to understand correctly. Is your current flowing through the surface, i.e. from dielectric 1 to dielectric 2, or along the surface without flowing through the dielectric? In the latter case, the "surface" would need a finite thickness anyway, wouldn't it?
